67) باب الصَّوْمِ يَوْمَ النَّحْرِ

حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا مُعَاذٌ، أَخْبَرَنَا ابْنُ عَوْنٍ، عَنْ زِيَادِ بْنِ جُبَيْرٍ، قَالَ جَاءَ رَجُلٌ إِلَى ابْنِ عُمَرَ ـ رضى الله عنهما ـ فَقَالَ رَجُلٌ نَذَرَ أَنْ يَصُومَ يَوْمًا، قَالَ أَظُنُّهُ قَالَ الاِثْنَيْنِ، فَوَافَقَ يَوْمَ عِيدٍ‏.‏ فَقَالَ ابْنُ عُمَرَ أَمَرَ اللَّهُ بِوَفَاءِ النَّذْرِ، وَنَهَى النَّبِيُّ صلى الله عليه وسلم عَنْ صَوْمِ هَذَا الْيَوْمِ‏.‏
